Hello,
Welcome to HCM,

Lyme disease is diagnosed clinically based on symptoms, physical examination or a history of exposure to infected ticks.

Lyme disease is caused by a bacteria Borrelia burgdorferi tests are available in serology to detect antibodies against this bacteria,the sensitive ELISA test is performed first, and if it is positive or equivocal, then the more specific Western blot is run.

PCR is also available.So you can get the tests done for confirmation.

I would suggest oral doxycycline, if you have taken this and if there is resistant to this you can take either cefuroxime or azithromycin.These medications should be taken for at least one to four weeks.
Thank you.
